“…Croatian populations and cultivars (TP 2,7; CD-3, Viva) and Serbian and German cultivars (K-17, Taifun) had higher tolerance to drought conditions observed by a higher productivity, even up to 35% higher yield, as compared to other tested materials. The high sensibility of red clover to environmental stress caused by drought was previously reported by Peterson et al (1992), Sheaffer and Seguin (2009), Lang and Vejražka (2012), Gaudin et al (2013) and Kizekova et al (2013). Seed yield was significantly different among studied cultivars and populations of red clover.…”

The frequency of extreme climatic events has increased due to global climate change. The objectives of this research were to investigate the influence of climatic conditions (precipitation and temperature) on productivity of red clover cultivars and populations with a different genetic background and to identify those with high forage yield potential in environmental stress. Twenty-three red clover cultivars and populations of different geographical origin were studied during two consecutive growing seasons (2012-extremely dry weather conditions, 2013-humid weather conditions) at the Agricultural Institute Osijek, Croatia. A field experiment was performed as a randomized block design with three replicates. Green mass and dry matter yield and plant height were measured in both growing seasons, whereas the seed yield was determined in the first year only. Results indicated the stability or adaptability of evaluated red clover cultivars and populations to a dry or humid weather production conditions. Croatian populations (CD-3, TP-2, TP-7) and cultivar Viva, Serbian cultivar K-17 and German cultivar Taifun exhibited the highest forage yield potential under both, dry and humid growing conditions and represent a valuable material to be used in red clover breeding programs dealing with tolerance to abiotic stress.

Background Prebreeding in plants is the activity designed to identify useful characteristics from wild germplasm and its integration in breeding programs. Prebreeding aims to introduce new variation into the populations of a species of interest. Pedigree analysis is a valuable tool for evaluation of variation in genebanks where pedigree maps are used to visualize and describe population structure and variation within these populations. Margot Forde Germplasm Centre (MFGC) is New Zealand’s national forage genebank and holds a collection of ~ 75 species of the genus Trifolium, of which only a dozen have been taken through prebreeding programs. The main objective of this study was to construct pedigree maps and analyse patterns of relatedness for seven minor Trifolium species accessions contained at the MFGC. These species are Trifolium ambiguum, Trifolium arvense, Trifolium dubium, Trifolium hybridum, Trifolium medium, Trifolium subterraneum and the Trifolium repens x Trifolium occidentale interspecific hybrids. We present a history of Trifolium spp. prebreeding in New Zealand and inform breeders of possible alternative forage species to use. Results Pedigree data from accessions introduced between 1950 and 2016 were used and filtered based on breeding activity. Kinship levels among Trifolium spp. remained below 8% and no inbreeding was found. Influential ancestors that contributed largely to populations structure were identified. The Australian cultivar ‘Monaro’ had a strong influence over the whole population of accessions in T. ambiguum. T. subterraneum and T. repens x T. occidentale had the largest number of generations (3). T. ambiguum and T. medium had the highest cumulative kinship across the decades. Conclusions We conclude that there are high levels of diversity in the seven Trifolium spp. studied. However, collection and prebreeding efforts must be strengthened to maximize utilization and bring useful genetic variation.
